This is track 12 of album fripSide PC game compilation vol. 2 called Passion Fruits. The album is from 2015. All the copyrights go to the artist fripSide. I don't own anything in this video.
Thanks for your comment. I uploaded it here because I noticed that it wasn't in the RU-vid at all. BTW Google translator is quite good nowadays because I'm actually trying to learn to speak Japanese but I don't know how read yet.
